Abstract

Electro process is applied for water and wastewater quality improvement usually based on electrocoagulation. It is a simple and effective method for water and wastewater treatment. It is an intention of this paper to present on a report of a study using electro process to improve wastewater quality, based on removals of colour, COD and suspended solids. A reactor made of a beaker, consists of iron plates as electrodes, a liter of solution sample, applied current density of between 35 A/m2 and 200 A/m2, with duration of between 5 minutes and 40 minutes. From the study it was shown that the reactor can remove colour, COD and SS by more than 80%, 80% and 30% respectively, with optimum duration of between 15 minutes and 30 minutes. The study also has shown that current density and duration most influent factors besides concentration of the solution sample.
